"toshow; the construction.

To an whom at may canoe f ew g i i es' de View. e'e; e ewu-as phl e 0th mat-helpe F gmyii h eve deik 3 is a rear view of the same, partly in section The object of this in vention isgtq-furni'sh an improved device for iattachmeutto the frames. or bodies of trucks, wagons-,= cars 860., to fa; cilitate the loading and unloading of said vehicles, and which shall be simple in construction and convenient in use. i

.The invention consists in .the combination of the pair of triangular or quadrantal plates and their shaft and roller, and the roller or rollers and its slotted and raised bearings, with the bottom or frame of a vehicle; in the combination of the second pair of triangular plates and their rod and roller with the first pair of triangular plates and their rod and roller, the roller and its slotted and raised bearings, and the bottom or frame of a vehicle; in the combination of the supporting plate or bar with either or both pairs of triangular plates and their shafts and rollers; in the combination of the connecting-rod and the lever, orequivalent device, with the forward triangular plates and their shafts and roller; in the combination of the connecting-rods, or

' their equivalent, with the two pairs of triangular plates and theirshafts and rollers; and in the combination of the two movable crossbars, the two swiveled crank-screws, and the two pivoted bars with the triangular plates and the upright 'bars or stakes attached to the bottom or frame scribed.

In the drawing, Arepresents the bottom or frame of the vehicle, to which, in front of its center, are pivoted two metal plates, B. The disks B are madein shape of triangles or quadrants of circles, and are pivoted at their angles by a shaft, 0, attached to said, plates, and which works in bearings attached as hereinafter fully defr m-eq a uc gcorners of the. disk-sI'B. are journaledwtheends .jof a. rollely D, upon which th'evforward part 30f*tl1e1l03. d.5reS1'/S,fl The middle parto'f theload ,rests upon one; orcmore-rollers, -E, ;res'tingrin bear ings;F, whichgmayi be slotted, iifcdesired, attached. to bl0'0kS*G,jWll-l(3l1 are attached-s-to ;--th egbpttom oi; frame-3A.; The. roller E serves as a pivot to -=.the' doad{when-beingtilted-hr j dumped, and -theislotted:bearingsj'F prevent 1 6: necessity-of sliding th e.;-load when *i-tsaforward end is raised in dumping, andi-thus :grnakes thebpe-ration ofzd'um-pi-ng mnch easier. ff he upperapart of one of theplatesiB fis pwoted: Fthe rear endasof 5a connecting-'rom fl, 1 the fqrward' end: of -awhicht's pivotedto a lover, I. The lower end of the lever I is pivoted to the bottom or frame A, and its upper end projects into such a position that it may be conveniently reached and operated by the driver. By this construction, by operating the lever l the forward end of the load is raised, so that it willreadily slide 01f.

' If desired, the plates B may be operated. by a wheel connected with them or their rod 0, and operated by a chain and vertical shaft in the same manner as car-brakes are operated. To support the rear end of the load While being carried, and give it more steadiness of motion while being tilted, a second pair of plates, J, with their shaft K and roller L, may be pivoted to the rear-part of the bottom or frame A, and connected with the forward pair of plates B by connecting-rods vM. In'case a body or box be used, the said body or box will serve to connect the two pairs of plates B J, and the connecting-rods M will not be required. To the rear edges of the rear plates upper edge of which projects'a little above the roller L, so that when the said disks are turned forward for carrying the load the said load may rest upon the said plate or bar N, and thus relieve the journals of the roller L.

The edge of the plate or bar N may be toothed or roughened to prevent the load from slipping upon it. In the same way the journals of the roller D may be relieved, and the forward end of the load supported by a bar attached to the bottom or frame A, or to the plates B.

J is attached a plate, board, or bar, N, the p 'lfTb' fie'bbtmmtr frarne L at a little distanhe from the pivoting-pin of the plates J,

are securely attached the lower ends of two uprights or stakes, O, the upper parts'of which pass through holes in the ends of'the two cross-bars P Q. The lower cross-bar P is sup-i ported adjustably by two crank-screws, B, the lower ends of which are swiveledtosaid cross-bar. The screws 1%. pass through screw holes in the upper cross-bar Q. The ends of the upper cross-bar project, have holes formed through -.them toreceive the upper parts LDf the bars S, and are secured to said bars'S by staples or other convenient fastenings or the bars Sinay he pivoted to the ends of the bars Q, if ldesired. The lower endsof the; ba-rs S are pivoted: to the plates J, g.

this construction, when thefjload is 1 arranged to be carried, the swiveled crank;- screwslt are turned 9 to force the lower cross.-

;b ar B down upon; the load, and thustbil d it in-place, When the load is tobei unloaded 1 or dumped the movementuof the plates J raises .the bars ,8 and the crossbars B Q, andvrel leases theloadautomatically. j
